EdemaSeverity [1]}: 6,524 examples from MIMIC-CXR with pulmonary edema severity labels (0 to 3, increasing severity) extracted from the radiology reports using a regex model [2]}, [3]}. Of these, 141 radiographs were examined by radiologists and consensus was reached on severity level (Fleiss' kappa: 0.42 individually, 0.97 consensus) [4]}. We use regex-labeled examples during pretraining and consensus examples during transfer.
